Just the smaller on
I suspect that someone will have to drill/ream some standard bore
pulleys for you to get 9mm.
I think that they will do that for you.
Click on the quote request and ask them to supply them with 9mm bores.

This is only true for the first-generation pulse coders, the later on
Yes sorry I was assuming he already had the machine and the drive went bad,
he was looking for an alternative. If this If this is the case all of the
wires brought to the existing drive are flying lead, so the encoder pulse
wire is already there. I have repaired several of the existing drives.

I think that Fanuc motors are AC synchronous (brushless permanent
magnet) so need a closed-loop drive.

Nice! That would make a nice spindle motor! I had no idea they could
turn that fast.

Hello Dave,
I found my 3 ph washer motor at a local metal recycler and paid about
$.50 per lb.
Here is a youtube video of my motor spinning up t
If you are using a low frequency PWM from EMC2 you may want to consider using
a DigiSpeed to control a VFD or DC motor controller such as the KB Electronics
range.
The DC-03 takes a PWM signal with a base frequency in the range of 5 - 50Hz.

That will work Thanks Kirk!

I looked at those motors once, but was stumped with finding a suitable power
supply. Where do you find a 12v 125A power supply? (or whatever it works

it has a pwm up/down mode.
I have goofed around with it a bit..

Thanks Dave and Kirk for your suggestions, they are food for
thought. The little motor I have will be powerful enough for
the time being and runs at 10,000rpm - almost all the
milling I do is with cutters of 3/16 and under - mostly 1mm
or less. I won't be using the motor as the spindle - I have

PWM out of a LPT port is about as cheap as you can get. 24 volts at 5
amps is only about 125 watts. Is that enough power?
Using a 120 volt universal motor with a PWM controller you can get
pretty high power for cheap. Universal motors (brushed wound rotor
motors) are fairly common.
